Breaker! Breaker!
Keyway = front of crank
That's what I thought. Didn't think the rear of the crank on our idi's would be any different from any other engine I've worked on. That's a relief as I wouldn't be able to see any evidence of a shop following the direction of "use some silicone on the keyway. I'll be doing the front myself, hopefully next year. I'm only going to have the shop do the rear while the transmission/clutch/flywheel are out.
So what about the rear seals? Since I haven't had an opportunity to dissect one of these engines, I'm not sure what I'm looking at. All the rear main seal kits that I find have the rear cover gasket and a rear seal that looks like it fits around the crank with no metal on it, just a squared off o-ring like I've seen on gas engines. But when I search the numbers listed above, I find steel backed seals, like one that would go on a spindle that gets pressed into a hub. So do I need one seal that goes around the crank flange inside the cover (that presses between the block/oil pan) and one that presses into the rear cover along with the gasket between the rear cover and block?
